摘　　要：The ranking system of grindability is the key technology for high-efficiency grinding granite. A new classification system is presented to evaluate and ranking the grindability of granite. On account of the complicated relation between the mineral composition and mechanical properties with the grindability of granite, a new method by the combination of Fuzzy Analytic Hierarchy Process (FAHP) method with TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) methods is developed to establish the dependence function and fuzzy relationship between SiO2 content, quartz content, Shore hardness, density, compressive strength, flexural strength and abrasion resistance of granite with grinding force. The grindability of ten types of granite was evaluated and classified by this method. With the fuzzy ranking system established and the grindability classification, it is very convenient to evaluate the grindability and select a suitable diamond tools and proper grinding parameters for a new granite type by only the petrographic analysis and mechanical properties testing.The ranking system of grindability is the key technology for high-efficiency grinding granite.
